A NEW DATA LOGGER Stand alone. Secure. Fast.

– A data logger for profe Extensive functions LogMessage data loggers are universal. Whatever the application – for slow or for high-speed acquisition – Delphin has a LogMessage version for any user requirements. Delivery includes the ProfiSignal Go software to enable professional evaluation of online and offline data. LogMessage devices function intuitively making it easy to configure inputs, to save data, and to display data as trends.

LogMessage devices are designed for permanent operation and can be depended on to perform reliably over the long term. When data security and reliability are top priorities, users choose the "Made in Germany" logger.

Universal sensor connection LogMessage devices are precision instruments that can be switched via software to function with any type of sensor. Universal use of analog inputs for mA-, mV-signals, RTDs, or any thermocouple Signal rate of 0.1 Hz to 10 kHz Digital inputs suitable for up to 90 VDC Frequency inputs up to 35 kHz

Galvanic isolation included LogMessage devices are fully protected against earth loops enabling measurements from non-isolated sources. All analog inputs can function as differential inputs Isolation voltage between analog inputs: 110 VDC to a maximum of 650 VDC Galvanic isolation between power supply and each interface No earth loop problems

Applications Secure data acquisition with stand alone capability

Fault diagnostics at machine/plant

PC-independent measurement and testing

Status and event logging

Acquisition via universal inputs

Energy efficiency measurements

Product testing, laboratory, R&D

GPS data logging and remote monitoring

Mobile data acquisition

Temperature data acquisition


Secure data storage The LogMessage's data storage capability enables it to function without PC or network support. 3.5 GB of memory for 250 million data records Each measurement data record is recorded with a time-stamp (date and time – at microsecond precision) Measurement data can be assigned to groups and used as triggers No data loss in the event of power failure Alarm management with pre and post alarm data

Comprehensive signal processing

RS232/485 20 mA Volt/mV RTD

Software channels, configurable according to requirements, can be used for online calculation, monitoring, and many other functions. This enables data to be generated that is immediately usable. Online calculations performed on measurement data (e.g. temperature differentials) Integration functions (e.g. flows to volumes) Limit value monitoring with alarm functions (switching digital outputs) Counter function and operational data acquisition

Resolutions for demanding requirements LogMessage devices are suitable for both slow- and high-speed measurements. Time resolution for analog measurement data is at 100-Âľs precision levels; digital resolution at millisecond precision. The devices are equipped for precision measurement with 24-Bit ADCs.

The LM 5000 version has an increased isolation voltage of up to 650 VDC between inputs.

Web server included LogMessage devices are equipped with internal web servers. The standard version displays current measurement data in a channel list as well as extensive configuration and maintenance information. In combination with the ProfiSignal WEB option, views can be generated and loaded into the LogMessage in HTML5.

Online analysis Calculation channel

Software channels Software channels are capable of performing computations on online measurement data, and used for visualisation, storage or monitoring purposes. The processing of signals takes place independently within the LogMessage device and requires no PC support. There is virtually no limit on the number of software channels that can be used. Software channel computations run parallel to data acquisition and logging. Software channels are included in delivery.

Channel averaging Edge counter Differentiator Integrator Linearization

Description Any number of channels can undergo computation procedures. Functions include: basic arithmetic functions; trigonometry; binary and boolean operations Computation of moving and triggered averages Counter for impulses (high, low, and reset functions) Computes changes over time

Numerical integration over time Corrective calculations on non-linear sensors Accumulates the time (in hours) of a digital signal's Operating hours counter high-level Computes moving and triggered statistical values Statistic channel (min, max, variant, standard deviation) Time measurement between two events Stopwatch

Monitoring Limit value Batch alarms Wake function Status monitoring

Description Generates events for threshold violations (over- / under-runs, inertia, hysteresis, process monitoring) Generates a single alarm from multiple input channels Generates pulses at a chronological point in time (once a day, week, month‌) Evaluates status information for measurement data and generates an alarm

– included Quick to deploy LogMessages are delivered with the professional PCsoftware ProfiSignal Go, used for online/offline monitoring and measurement data analysis. Just three steps are required to display measurement data as trends, to analyse the data, and to evaluate offline data.

with ProfiSignal Go, the DataService also provides many alarm management and monitoring functions. The DataService enables ProfiSignal to function efficiently and powerfully as well as to process large data volumes via multiple and diverse interfaces.

ProfiSignal Go has a choice of diagrams that can be run simultaneously. The integrated DataService software provides data storage and archiving functions. In combination
